Consider a static service rate control problem for M/M/∞ system
with arrival rate λ. The system can choose a service rate μ that is
common to all the servers and fixed over time. There are two types
of costs associated: (i) a service-cost rate c (cost per unit time
per unit service rate); and (ii) a holding-cost rate h (cost per
unit time per customer in system). Note that the service-cost rate
here is the cost rate for all servers together. What is the optimal
service rate �∗?
